group DS1CARR
Measurement list
CARRERR uses the sum of DS1CARR measurements DS1BER, DS1LOF,
and DS1SLP. In International offices, this index uses the sum of
PCMCARR measurements LLFAERR, LLMAERR, RFAIERR, RMAIERR,
AISERR, BERERR, SLIPERR, SIGLERR, CRC4ERR, AIS16ERR,
LLCMAERR, and CREERR.
Normalizer
CARRERR is normalized per working digital carrier link per unit time.
Diagnostics
Check OM group DS1CARR measurements DS1BER, DS1LOF, and
DS1RCGA. Also check logs PM110 and PM112 when the maintenance or
out-of-service threshold has been exceeded. Check the DS1CARR menu for
carrier (CXR) trouble.
